The ball cutter comprises a cutter bar, a scrap-discharging groove, a cutter bit, a cutter bit base, a mounting part, through holes, a mounting slot, a blade, a cutting edge, a cutter handle, a key slot and a positioning concave hole. The ball cutter has the following beneficial effects: the blade is detachably connected with the mounting part in the manner of blocking in the mounting slot, so that the blade can be conveniently mounted and dismounted; two through holes are formed on both of the mounting part and the blade; the through holes on the mounting part and the blade are one-to-one corresponding to each other, so that the blade blocked in the mounting part can be conveniently mounted and fixed; the shape of the cutting edge of the blade is matched with a pre-molding structure of a to-be-processed workpiece part; the processing effect can be achieved by one-time processing; the cutting edge is equipped with positive and negative blade surface
